Students and scientists investigate soils through the collection of data using measurement protocols and using instruments that meet certain specifications in order to ensure that data are comparable. Learning activities aid in the understanding of important scientific concepts, the understanding of data, and data collection methodologies. The Investigation appendix contains data sheets for all land cover and biology protocols, a soil textural triangle and a glossary of terms. Additionally, data sheets (from the Appendix) and field guides (from the individual protocols) are available individually.
The GLOBE Soil investigation is available in the six United Nations languages (select any of the following links to open the corresponding document): Arabic, Chinese (1997 edition), English, French, Portuguese (1997 edition), Russian (1997 edition), and Spanish.
